Problem: Passing Variables and Functions through Frames on a Template Page?

Hello all, First, sorry for the long message but I wanted to provide as much detail as possible. I have been developing an application on windows 98 + PHP Triad (PHP 4.0, MySQL 3.23.10a, Apache 1.3.12 (Win 32). The application is working great on my local computer, but then I loaded to my web host which is running Linux (latest Red Hat), PHP 4.0, MySQL 3.23.18a, Apache 1.3.12. Moving on to the problem: THE WAY IT WORKS ON MY DEV. COMPUTER My application sets a session variable after login and authorization and then directs the user to the template page. The main include file (with my functions) is then called and all of the frames are loaded. Because I have called the main include file at the beginning of this page, I don't have to call it again. In fact I would get an error if I tried to call it in any of the frames because it says I am calling a function twice. Additionally, my variables that were passed to the template page from the login script are used in some of the frames on the template page. For example, in the main content area, I run a checkSession() function that clears out old functions and refreshes the currently active function. It also gets the user information from the session id and personalizes this "default content" page. THE WAY IT WORKS ON MY HOST The authorization script runs and assigns a session id. The template page loads everything except the main content page which returns an errors stating that the functions aren't declared. This implied that the main include file wasn't loaded into the frame. To debug, I included the file in the main content frame. I did not receive an error message. The next problem in the main content page was with the checkSession() function which did not run, because the session id is not being passed into this frame either. Trying to debug, I hard coded a good session variable into the frame. Now some of my functions work but some don't. For example, in my checkSession() function, the sub function that clears old sessions after 10 minutes fails yet the last action for the sessionid is updated. To summarize, does anyone know why on my win98, PHP Triad environment the variables and functions are sent inside frames but in the Linux environment none of this is happening correctly? Has anyone had this problem and is their a fix. My next step is to begin a reasonably large re-write of my app. Thx, Paul
